Performance of radar assisted satellite based automated train transit system

In this article, we present the performance of an automated train transit system using radars and a Geo stationary satellite. The Radars placed along the railway tracks update the accurate speed and position of the train to the central base station which controls the trains over a wide geographic region. The central base station directs the train by communicating via a Geo stationary satellite. The proposed system model does not require visible signaling for trains. It also eliminates the possibility of a collision between two trains. Further, the use of multiple radars ensures that system doesn´t fail, even if any of the radar fails. Our performance study shows that the effect of rain on the satellite link requires at least a 5dB additional signal to noise ratio (SNR) at the receiver to maintain the same bit error rate (BER).
